To support my HF long-wire, I have been using a similar arrangement here
but, in
addition, I have connected a spring "in series" with the pulley, to absorb
small
shocks. This arrangement has served me well for the last 3 years.
I use both of these methods, using a smooth metal hoop instead of a pulley,
but it's the same principle. The secret is to avoid anything that gradually
saws the rope. The springs on my antenna are bungee cords used for tying
suitcases. Also, one of my masts is very springy. It all looks a bit
frightening as it moves around in the wind, but so far it has stayed up. The
bars that separate the three parallel top wires have been twisted, however.
My neighbour has lost part of his fence and another has lost a tree. The
town is strewn with fallen branches. Several local roads are partly blocked
by fallen trees.
I may regret writing this as the wind is getting stronger again.
